Reversible blanket



Nov. 21, 1961 w. v. M CRARY REVERSIBLE BLANKET Filed Feb. 18, 1957REPEAT 01- PM LING i g. 3 INVEN TOR. a e W/LLIAM K MCCRARY BY StatesPate This invention relates to Woven blankets, and more particularly toan improved weave construction by which reversible faces (i.e., faces ofdifferent color) may be formed eifectively in a lightweight blanketstructure.

The improved weave construction of the present invention ischaracterized by a double weave in which a relatively high warp densityis employed, but in which a majority of the warp is arranged in floatingrelation at each filling pick so that the pick count can be reducedsubstantially without encountering subsequent difiiculty in preventingdifferent colored fillings at the opposite faces of the weave frombleeding through upon napping.

More specifically, the double weave of the present in vention isarranged with each warp end running alternately under a group of fourtop face and one bottom face filling picks and over a group of one topface and four bottom face filling picks, and with any five adjacent warpends disposed l-up in relation to any top face filling pick, l-down inrelation to any bottom face filling pick, and three ends floating inrelation to all filling picks.

These and other features of the present invention are described infurther detail below in connection with the v accompanying drawings, inwhich:

FIG. 1 is a pattern chart for the improved double weave construction ofthe present invention;

FIG. 2 is a fragmentary diagram illustrating the relative interlacing ofany five adjacent warp ends in a blanket cloth incorporating the weaveconstruction of the present invention; and

FIG. 3 is a further fragmentary diagram illustrating the warp endarrangement fillingwise at a pair of top and bottom face filling picks.

In the pattern chart of FIG. 1 the warp ends are shown repeating ingroups of five adjacent ends designated by the reference characters a,b, c, d and e (the warp end being up at the marked squares), and therepeat of the filling is shown to include 20 picks indicated by thereference numerals l to 20, inclusive. As it is a reversible blanketthat is being formed by the double weave construction of the presentinvention, the top and bottom filling picks are formed with differentcolored yarn and the filling pick sequence must be arranged so that theshooting and return picks run in pairs of the same color. Accordingly,the filling pick 1 in FIG. 1 and throughout the remainder of thedrawings, is illustrated as being the return pick of the top facefilling color, while filling picks 2 and 3 are in turn the shooting andreturn bottom face picks of the other color, filling picks 4 and 5 arethe shooting and return top face filling picks of the first color, andso on. On this basis, picks 1, 4, 5, 8, 9, 12, 13, 16, 17 and 2t) aretop face filling picks, and picks 2, 3, 6, .7 it), 11, 14, l5, l8 and 19are bottom face filling picks.

As previously mentioned, the double weave construction of the presentinvention is characterized first by an arrangement of the warp in a4l-14 pattern; that is, with each warp end a, b, c, d and e runningalternately under a group of four top face and one bottom face fillingpicks and over a group of one top face and four bottom face fillingpicks. This warp arrangement is illustrated in FIG. 2 of the drawings inwhich the group of five warp ends and each of the bottomface fillingpicks being tied-in above a different warp end in running arrangement ofeach warp end a, b, c, d and e is separately represented in schematicfashion based on the pattern chart of FIG. 1. FIG. 3 further illustratesthe fillingwise arrangement of the repeating groups of adjacent warpends a, b, c, d and e to indicate the nature of the resulting weavestructure at a pair of bottom and top face filling picks 19 and 20.

It has also been noted previously that while the above noted warparrangement involves a relatively high Warp density, a majority of thewarp is maintained in floating relation at each filling pick, and thisfeature of the double weave construction provided by the presentinvention is demonstrated in FIG. 3 in which it will be seen that anyfive adjacent 'warp' ends are disposed l-up in relation to any top facefilling pick (such as 20), l-down in relation to any bottom face fillingpick (such as 19), and three ends floating in relation to all fillingpicks (such as 19 and 20), so that the floating warp exceeds thetying-down Warp by 50%.

As a result of this arrangement, the warp density in the weaveconstruction of the present invention may be increased in the order of25%, while still avoiding the boardiness that usually results fromincreased warp density, by maintaining a majority of the warp floatingin the above noted manner. A further result of this preponderantfloating arrangement in the warp is to allow a substantial reduction inthe filling pick count so as to obtain a lightweight weave constructionwhile at the same time disposing the filling at the opposite faces ofthe double weave for effective napping without difiiculty with bleedingthrough of the different colored top and bottom face fillings to theopposite faces.

As a representative example, a reversible blanket may be formedadvantageously according to the present invention with warp consistingof cotton yarn having a count of 20s/1 and using a 2/225 reed to providean initial warp density of 45 ends per inch (that would becomeapproximately 46 warp ends per inch off the loom, and 50 ends per inchin the finished blanket), and was a blended rayon filling having a countof 2.85s used at a pick count of. 33 picks per inch. The resultingblanket cloth forms a 3 lb. blanket, which indicates the lightweightconstruction possible according to the present invention, although thebulk and napping qualities of this lightweight blanket cloth areexceptional so as to provide a warm blanket structure despite thelightness of the weave construction and the substantially reducedfilling pick count.

The present invention has been described in detail above for purposes ofillustration only and is not intended to be limited by this descriptionor otherwise except as defined in the appended claims.
